Computer vision syndrome (CVS) is a set of eye and vision-related symptoms after prolonged use of digital devices like computers, tablets, e-readers, and mobile phones.
CVS can cause various ocular problems, including blurred vision, headaches, fatigue, and dry eyes. It can also cause musculoskeletal issues such as back pain and neck stiffness.
Blurred vision
Blurred vision is a common symptom that several different eye conditions may cause. It is vital to get your eyes checked by a professional if you notice any changes in your vision, as some causes of blurred vision, can be treated and prevent further damage.
During an eye exam, the doctor will ask questions about your computer vision syndrome symptoms and medical history. They may also do a physical examination to check your vision, reflexes, muscle strength, sensation, and coordination.
The doctor will then test your understanding (visual ability to see fine details) to find out what is causing the blurry vision. If the refractive error is the cause of the blurry vision, corrective lenses can correct the problem and make you see again.
You should get immediate medical attention if a more severe condition causes blurred vision. For example, it could be glaucoma, which needs to be treated quickly, or progressive eye disease, which can lead to permanent vision loss.
Many causes of blurred vision can be treated with corrective lenses or surgery. However, others may require treatment by a specialist to ensure you get your best possible vision. These include a variety of retinal disorders and diseases and some neurological problems.
Headaches
Computer vision syndrome (CVS) is a condition that causes pain, discomfort, and headaches when you spend too much time looking at digital screens. It can be challenging to avoid, but some ways exist to ease and prevent this common problem.
If you have CVS, your doctor might recommend eyeglasses or contact lenses specially made for computer use. They may also prescribe some visual training, such as vision therapy, to help your eyes work together better and improve your ability to see clearly.
Taking regular breaks from screens and blinking often can relieve the symptoms of CVS. Practicing the 20-20-20 rule will also help reduce the strain on your eyes.
Your doctor may be able to prescribe medications for the symptoms of CVS. They might also suggest lifestyle changes, such as reducing your screen time daily and getting more physical activity.
Blurred vision is another symptom of CVS. Several factors, including dry eyes, eye fatigue, and poor vision correction, can cause it.
Sudden changes in your vision can indicate a more severe optical or neurological issue. It is why it’s essential to see your doctor if you experience sudden vision changes, especially if you haven’t had them before.
Eye fatigue
Computer vision syndrome combines eye and vision-related problems associated with prolonged computer use. It can affect any age group, but it is more common in people who use computers or digital devices for extended periods.
The eyes naturally blink about 18 times a minute to refresh and keep them from feeling tired. However, studies have shown that when you use a computer or other digital device for long periods, you only blink half as often as usual.
It can lead to dry, itchy, and burning eyes and may make you feel more tired. It also can decrease your productivity and may cause a headache.
In some cases, eye fatigue is caused by unconsciously clenching the muscles of your eyelids, face, temples, and jaws while trying to perform an intense visual task. It can lead to discomfort, pain, and even more severe asthenopia.
It could be time to see your doctor when this condition is not relieved by resting, adjusting lighting, or other at-home treatments. It is especially true if you experience lingering symptoms like blurred vision, double vision, or frequent headaches.
Eye fatigue can be treated by reducing screen time, adjusting applicable lighting, and taking breaks every 20 minutes. It is also a good idea to get a comprehensive eye exam. It will help your doctor determine the cause of your eye strain and recommend the appropriate treatment.
Dry eyes
Dry eyes are a common problem commonly caused by low production or poor tears quality. Symptoms include burning, itching, and gritty sensations in the eye. This condition can be treated with artificial tear drops, lubricant creams, or both.
Some people are born with inadequate tear production or underlying medical conditions that affect the amount and quality of tears they produce. These people may need a comprehensive eye examination by a vision specialist to determine the cause of their symptoms and whether they need to make other lifestyle changes.
Other problems can be caused by how computer monitors and digital devices are set up or by the distance between the computer screen and the user’s eyes. It can make it harder to see and cause other physical strain that leads to ocular, head, and neck pain.
Another dry eye cause is low humidity, fumes, or dusty air exposure. Changing your environment to a more humid or less dusty place can help reduce the irritation and fatigue that can lead to computer vision syndrome.
